[Gluster-users] Problems with self heal on replicated DHT

[Roland Rabben]

Hi
I will try to check out 3.0.0 on a different system.

I now see that self heal works if i try to self heal the missing file
directly instead of self healing the folder containing the missing file.
E.g.
ls -lR mymissingfile

This will bring the file back.

ls -lR myfolder

This will not bring the file back.

It is still a big hassle to locate the missing files and run individual
commands to fix these rather than just one self heal command across the
entire dfs.

Regards
Roland
